FULL STORY

New research presented at the 73rd Annual Scientific Meeting of the American College of Gastroenterology in Orlando found patients with inflammatory bowel disease or chronic liver disease were at increased risk of developing Vitamin D deficiencies. Two separate studies highlight the importance of regular Vitamin D checkups in the evaluation of patients with certain digestive diseases.

For IBD Patients, Vitamin D Deficiency Associated with Lower Quality of Life and Higher Disease Activity

Researchers at the Medical College of Wisconsin investigated whether Vitamin D deficiency in patients with IBD is associated with a lower quality of life or higher disease activity independent of other known risk factors and medication use.

Disease activity and quality of life were assessed using validated questionnaires, which were administered at every clinic visit. The researchers also looked at the prevalence and seasonality of Vitamin D deficiency in this inflammatory bowel disease population, as well as its association with IBD-related hospitalizations, surgeries and medication use.

This retrospective cohort study conducted by Dr. Alex Ulitsky and his colleagues analyzed vitamin D levels of 504 inflammatory bowel disease patients. They recorded the patients' lowest Vitamin D measurements and date when each low measurement was taken.

Dr. Ulitsky and his team found almost 50 percent of the patients were Vitamin D deficient at some point, with 11 percent being severely deficient. Vitamin D deficiency was not significantly associated with being hospitalized for IBD or having IBD-related surgeries. However, in both Crohn's disease (CD) and ulcerative colitis (UC) patients, vitamin D deficiency was independently associated with having increased disease activity scores compared to those with normal levels of Vitamin D. Vitamin D deficient CD patients, but not UC patients, had worse quality of life when compared to patients who were not Vitamin D deficient.

According to Dr. Ulitsky, "All IBD patients, irrespective of their disease, disease location or nature should have their Vitamin D levels checked regularly and corrected aggressively when insufficiency is found."

Vitamin D Deficiency Prevalent in Patients with Chronic Liver Disease

Researchers from the University of Tennessee in Memphis measured the vitamin D levels of 118 chronic liver disease patients. Researchers found 92.4 percent of chronic liver patients had some degree of vitamin D deficiency and at least one third were severely deficient. Severe vitamin D deficiency was more common among cirrhotics.

"Since deficiency is common among these patients, Vitamin D replacement may hopefully prevent osteoporosis and other bone complications related to end stage liver disease," said lead researcher Dr. Satheesh P. Nair.

Vitamin D, a fat-soluble vitamin, helps the body absorb calcium and plays a crucial role in the growth and maintenance of strong, healthy bones. A lack of vitamin D causes calcium-depleted bone, which can weaken the bones and increase the risk of fractures resulting from osteoporosis.

A diet rich in vitamin D, such as fish, eggs, fortified milk, and cod liver oil, is essential to maintaining good bone health.
